Mail server, mobile communication system, and program therefor
摘要:
The present invention provides a technique for regulating the distribution of bulk and unsolicited e-mails without hampering convenience for both source and destination mail clients as much as possible. According to this technique, if the number of e-mails sent from either of mobile phones 10a to 10c exceeds a predetermined threshold, only e-mails which are addressed to specific mail addresses pre-stored in mail server 30 are disposed of.
